Godot Shaders Basics

A solid foundation for Godot shader work with practical patterns you'll actually reuse. Covers the usual suspects like dissolve and outline effects, but the real value is in the expert templates: instance uniforms for batched hit flashes, alpha scissor for performant foliage, and depth buffer reconstruction for volumetric effects. The "NEVER" section alone is worth scanning before you ship, especially the warnings about discard performance traps and Godot 4.3's Reversed-Z quirks. If you're moving beyond shader tutorials into production rendering, the patterns for triplanar mapping and global uniforms will save you from reinventing them poorly. Not comprehensive, but hits the common pain points.
